Abstract
Nucleolin (NCL) is a prevalent and widely distributed nucleolar protein in cells. While primarily located in the nucleolus, NCL is also found within the nucleoplasm, cytoplasm, and even on the cell surface. NCL's unique nature arises from its multifaceted roles and extensive interactions with various proteins. The structural stability of NCL is reliant on protease inhibitors, particularly in proliferating cells, indicating its essential role in cellular maintenance. This review is centered on elucidating the structure of NCL, its significance in host-viral interactions, and its various contributions to viral progeny production. This work is to enhance the scientific community's understanding of NCL functionality and its implications for viral infection processes. NCL is highlighted as a crucial host protein that viruses frequently target, exploiting it to support their own life cycles and establish infections. Understanding these interactions is key to identifying NCL's role in viral pathogenesis and its potential as a therapeutic target. Our current knowledge, alongside extensive scientific literature, underscores the critical role of host proteins like NCL in both viral infections and other diseases. As a target for viral exploitation, NCL supports viral replication and survival, making it a promising candidate for therapeutic intervention. By delving deeper into the intricacies of NCL-viral protein interactions, researchers may uncover effective antiviral mechanisms. This review aspires to inspire further research into NCL's role in viral infections and promote advancements in antiviral therapeutic development.
